About 8.2 on my diesel pusher. Like they say "not too good for a vehicle, but pretty good for a house".

Don't know what it costs to rent a car today, but the fact you bring yours along offsets that lousy 6 to 8 miles per gallon!

Another 1000 miles and pushing 13-14mpg. Last couple trips following a friend with a gasser (newer 30 fleetwood class A), he needed to fill up three times during our trip and dump tanks twice. I did not need to do either, it left him with what he calls Tank Envy.

I just returned from a 1500 mile trip up the Oregon Coast. Mileage was exactly the same as when I went across country...7.9 MPG. I figure it all manually.

Diesel Fuel Mileage

2010 Serrano, Between 10 and 13 MPG. This is driving in the Colorado Mountains also. I can`t believe it either,but it`s true! I`m used to getting 5-7 MPG on my Gas Unit.

Can you tellme what engine and transmission you have? Also did you set the transmission or do anything special . The Allision section of the handbook talks about setting the gears.... Got me confused. How much do you estimate your weight to be . Near 13 mpg in mountains unless you were descending the whole ride is startling.

2010 Serrano fuel mileage

It has the Workhorse V-8 Diesel, I have done nothing to the Tranny,and drive around 55-60. I also am amazed and unless I lost a couple of receipts
that is the mileage.
I will be taking a trip in the Arizona Mountains this weekend and will double check the mileage. As far as descending,it seems to be a push,You are going up as much as down.

We run 72 mph when road conditions permit ( faster when we're speeding up to pass yet another Prevost!!), run generator when needed, and tow the Jeep, lifetime average over 17k miles is 5.9 mpg per the trip tek. We figure that it costs around 17 cents more per mile to run than our 400hp coaches did. So on a 300 mile driving day that's around 50 bucks more per day, the extra power/weight is expensive, and that's before we add in the cost of the DEF fluid.

Wish my tires were rated for that. 65 is all I can get away with
